970fac5e24 gitweb: Give side-by-side diff extra CSS styling
Use separate background colors for pure removal, pure addition and
change for side-by-side diff.  This makes reading such diff easier,
allowing to easily distinguish empty lines in diff from vertical
whitespace used to align chunk blocks.

Note that if lines in diff were numbered, the absence of line numbers
[for one side] would help in distinguishing empty lines from vertical
align.

6ba1eb51b9 gitweb: Add a feature to show side-by-side diff
This commits adds to support for showing "side-by-side" style diff.
Currently you have to hand-craft the URL; navigation for selecting
diff style is to be added in the next commit.

The diff output in unified format from "git diff-tree" is reorganized to
side-by-side style chunk by chunk with format_sidebyside_diff_chunk().
This reorganization requires knowledge about diff line classification,
so format_diff_line() was renamed to process_diff_line(), and changed to
return tuple (list) consisting of class of diff line and of
HTML-formatted (but not wrapped in <div class="diff ...">...</div>) diff
line.  Wrapping is now done by caller, i.e. git_patchset_body().

Gitweb uses float+margin CSS-based layout for "side by side" diff.

You can specify style of diff with "ds" ('diff_style') query
parameter.  Currently supported values are 'inline' and 'sidebyside';
the default is 'inline'.

Another solution would be to use "opt" ('extra_options') for that...
though current use of it in gitweb seems to suggest that "opt" is more
about passing extra options to underlying git commands, and "git diff"
doesn't support '--side-by-side' like GNU diff does, (yet?).

f1310cf5e7 gitweb: Extract formatting of diff chunk header
Refactor main parts of HTML-formatting for diff chunk headers
(formatting means here adding links and syntax hightlighting) into
separate subroutines:

 * format_unidiff_chunk_header for ordinary diff,
 * format_cc_diff_chunk_header for combined diff
   (more than one parent)

This makes format_diff_line() subroutine easier to follow.

20a864cd83 gitweb: Refactor diff body line classification
Simplify classification of diff line body in format_diff_line(),
replacing two long if-elsif chains (one for ordinary diff and one for
combined diff of a merge commit) with a single regexp match.  Refactor
this code into diff_line_class() function.

While at it:

* Fix an artifact in that $diff_class included leading space to be
  able to compose classes like this "class=\"diff$diff_class\"', even
  when $diff_class was an empty string.  This made code unnecessary
  ugly: $diff_class is now just class name or an empty string.

* Introduce "ctx" class for context lines ($diff_class was set to ""
  in this case before this commit).

Idea and initial code by Junio C Hamano, polish and testing by Jakub
Narebski.  Inspired by patch adding side-by-side diff by Kato Kazuyoshi,
which required $diff_class to be name of class without extra space.

0866786b80 gitweb: Strip non-printable characters from syntax highlighter output
The current code, as is, passes control characters, such as form-feed
(^L) to highlight which then passes it through to the browser.  User
agents (web browsers) that support 'application/xhtml+xml' usually
require that web pages declared as XHTML and with this mimetype are
well-formed XML.  Unescaped control characters cannot appear within a
contents of a valid XML document.

This will cause the browser to display one of the following warnings:

* Safari v5.1 (6534.50) & Google Chrome v13.0.782.112:

   This page contains the following errors:

   error on line 657 at column 38: PCDATA invalid Char value 12
   Below is a rendering of the page up to the first error.

* Mozilla Firefox 3.6.19 & Mozilla Firefox 5.0:

   XML Parsing Error: not well-formed
   Location:
   http://path/to/git/repo/blah/blah

Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7
using arch/ia64/kernel/unwind.c from the Linux kernel.

When syntax highlighter is not used, control characters are replaced
by esc_html(), but with syntax highlighter they were passed through to
browser (to_utf8() doesn't remove control characters).

Introduce sanitize() subroutine which strips forbidden characters, but
does not perform HTML escaping, and use it in git_blob() to sanitize
syntax highlighter output for XHTML.

Note that excluding "\t" (U+0009), "\n" (U+000A) and "\r" (U+000D) is
not strictly necessary, atleast for currently the only callsite: "\t"
tabs are replaced by spaces by untabify(), "\n" is stripped from each
line before processing it, and replacing "\r" could be considered
improvement.

131d6afcba gitweb: Introduce common system-wide settings for convenience
Because of backward compatibility we cannot change gitweb to always
use /etc/gitweb.conf (i.e. even if gitweb_config.perl exists).  For
common system-wide settings we therefore need separate configuration
file: /etc/gitweb-common.conf.

Long description:

gitweb currently obtains configuration from the following sources:

  1. per-instance configuration file (default: gitweb_conf.perl)
  2. system-wide configuration file (default: /etc/gitweb.conf)

If per-instance configuration file exists, then system-wide
configuration is _not used at all_.  This is quite untypical and
suprising behavior.

Moreover it is different from way git itself treats /etc/git.conf.  It
reads in stuff from /etc/git.conf and then local repos can change or
override things as needed.  In fact this is quite beneficial, because
it gives site admins a simple and easy way to give an automatic hint
to a repo about things the admin would like.

On the other hand changing current behavior may lead to the situation,
where something in /etc/gitweb.conf may interfere with unintended
interaction in the local repository.  One solution would be to
_require_ to do explicit include; with read_config_file() it is now
easy, as described in gitweb/README (description introduced in this
commit).

But as J.H. noticed we cannot ask people to modify their per-instance
gitweb config file to include system-wide settings, nor we can require
them to do this.

Therefore, as proposed by Junio, for gitweb to have centralized config
elements while retaining backwards compatibility, introduce separate
common system-wide configuration file, by default /etc/gitweb-common.conf

e8c3531717 gitweb: Serve */*+xml 'blob_plain' as text/plain with $prevent_xss
Enhance usability of 'blob_plain' view protection against XSS attacks
(enabled by setting $prevent_xss to true) by serving contents inline
as safe 'text/plain' mimetype where possible, instead of serving with
"Content-Disposition: attachment" to make sure they don't run in
gitweb's security domain.

This patch broadens downgrading to 'text/plain' further, to any
*/*+xml mimetype.  This includes:

  application/xhtml+xml    (*.xhtml, *.xht)
  application/atom+xml     (*.atom)
  application/rss+xml      (*.rss)
  application/mathml+xm    (*.mathml)
  application/docbook+xml  (*.docbook)
  image/svg+xml            (*.svg, *.svgz)

Probably most useful is serving XHTML files as text/plain in
'blob_plain' view, directly viewable.

Because file with 'image/svg+xml' mimetype can be compressed SVGZ
file, we have to check if */*+xml really is text file, via '-T $fd'.

86afbd02c8 gitweb: Serve text/* 'blob_plain' as text/plain with $prevent_xss
One of mechanism enabled by setting $prevent_xss to true is 'blob_plain'
view protection.  With XSS prevention on, blobs of all types except a
few known safe ones are served with "Content-Disposition: attachment" to
make sure they don't run in our security domain.

Instead of serving text/* type files, except text/plain (and including
text/html), as attachements, downgrade it to text/plain.  This way HTML
pages in 'blob_plain' (raw) view would be displayed in browser, but
safely as a source, and not asked to be saved.

 * printing <link ...> elements in HTML head into print_header_links()

1ae05be4aa gitweb: Make git_search_* subroutines render whole pages
Move git_header_html() and git_footer_html() invocation from git_search()
to individual git_search_* subroutines.

While at it, reorganize search-related code a bit, moving invoking of git
commands before any output is generated.

This has the following advantages:

  * gitweb now shows an error page if there was unknown search type
    (evaluate_and_validate_params checks only that it looks sanely);
    remember that we shouldn't call die_error after any output.

  * git_search_message is now safe agains die_error in parse_commits
    (though this is very unlikely).

  * gitweb now can check errors while invoking git commands and show
    error page (again, quite unlikely).

2c162b56f3 gitweb: do not misparse nonnumeric content tag files that contain a digit
v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are
handled, 2011-04-29) tried to make gitweb's tag cloud feature more
intuitive for webmasters by checking whether the ctags/<label> under
a project's .git dir contains a number (representing the strength of
association to <label>) before treating it as one.

With that change, after putting '$feature{'ctags'}{'default'} = [1];'
in your $GITWEB_CONFIG, you could do

	echo Linux >.git/ctags/linux

and gitweb would treat that as a request to tag the current repository
with the Linux tag, instead of the previous behavior of writing an
error page embedded in the projects list that triggers error messages
from Chromium and Firefox about malformed XML.

Unfortunately the pattern (\d+) used to match numbers is too loose,
and the "XML declaration allowed only at the start of the document"
error can still be experienced if you write "Linux-2.6" in place of
"Linux" in the example above.  Fix it by tightening the pattern to
^\d+$.

2e987f9240 gitweb: Make JavaScript ability to adjust timezones configurable
Configure JavaScript-based ability to select common timezone for git
dates via %feature mechanism, namely 'javascript-timezone' feature.

The following settings are configurable:
* default timezone (defaults to 'local' i.e. browser timezone);
  this also can function as a way to disable this ability,
  by setting it to false-ish value (undef or '')
* name of cookie to store user's choice of timezone
* class name to mark dates

NOTE: This is a bit of abuse of %feature system, which can store only
sequence of values, rather than dictionary (hash); usually but not
always only a single value is used.

This will modify HTML, add CSS rules and add DOM event handlers so
that clicking on any date (the common part, not the localtime part)
will display a drop down menu to choose the timezone to change to.

Currently menu displays only the following timezones:

  utc
  local
  -1200
  -1100
  ...
  +1100
  +1200
  +1300
  +1400

In timezone selection menu each timezone is +1hr to the previous.  The
code is capable of handling fractional timezones, but those have not
been added to the menu.

All changes are saved to a cookie, so page changes and closing /
reopening browser retains the last known timezone setting used.

[jn: Changed from innerHTML to DOM, moved to event delegation for
onclick to trigger menu, added close button and cookie refreshing]

patch series entitled "gitweb: introduce localtime feature".  While
Kevin's patch changed the server side output so that the timezone
was output from gitweb itself, this has a number of drawbacks, in
particular with respect to gitweb-caching.

This patch takes the same basic goal, display the appropriate times in
a given common timezone, and implements it in JavaScript.  This
requires adding / using a new class, "datetime", to be able to find
elements to be adjusted from JavaScript.  Appropriate dates are
wrapped in a span with this class.

Timezone to be used can be retrieved from "gitweb_tz" cookie, though
currently there is no way to set / manipulate this cookie from gitweb;
this is left for later commit.

Valid timezones, currently, are: "utc", "local" (which means that
timezone is taken from browser), and "+/-ZZZZ" numeric timezone as in
RFC-2822.  Default timezone is "local" (currently not configurable,
left for later commit).

Fallback (should JavaScript not be enabled) is to treat dates as they
have been and display them, only, in UTC.

Pages affected:
* 'summary' view, "last change" field (commit time from latest change)
* 'log' view, author time
* 'commit' and 'commitdiff' views, author/committer time
* 'tag' view, tagger time

ce71b07632 gitweb: Unify the way long timestamp is displayed
format_timestamp_html loses its "-localtime => 1" option, and now
always print the local time (in author/comitter/tagger local
timezone), with "atnight" warning if needed.

This means that both 'summary' and 'log' views now display localtime.
In the case of 'log' view this can be thought as an improvement, as
now one can easily see which commits in a series are made "atnight"
and should be examined closer.

256b7b4883 gitweb: Refactor generating of long dates into format_timestamp_html
It is pure refactoring and doesn't change gitweb output, though this
could potentially affect 'summary', 'log', and 'commit'-like views
('commit', 'commitdiff', 'tag').

Remove print_local_time and format_local_time, as their use is now
replaced (indirectly) by using format_timestamp_html.

While at it improve whitespace formatting.

12b1443c2c gitweb: Restructure projects list generation
Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.

Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects.  Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.

Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed).  Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.

Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.

The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results).  If 'ctags' feature is disabled, then searching by tag is
too.

The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.

Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.

While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.

d940c9015d gitweb: Optional grouping of projects by category
This adds the $projects_list_group_categories option which, if enabled,
will result in grouping projects by category on the project list page.
The category is specified for each project by the $GIT_DIR/category file
or the 'gitweb.category' variable in its configuration file. By default,
projects are put in the $project_list_default_category category.

Note:
- Categories are always sorted alphabetically, with projects in
  each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
  category headers are only displayed for projects present on the page.

The feature is inspired from Sham Chukoury's patch for the XMMS2
gitweb, but has been rewritten for the current gitweb code. The CSS
for categories is inspired from Gustavo Sverzut Barbieri's patch to
group projects by path.

Thanks to Florian Ragwitz for Perl tips.

[jn: Updated to post restructuring projects list generation, fixed bugs,
 added very basic test in t9500 that there are no warnings from Perl.]

It might have been hard to discover that current view is limited to
projects with given content tag (ctag), as it was distinquished only
in gitweb URL.  Mark matched contents tag in the tag cloud using
"match" class, for easier discovery.

This commit introduces a bit of further code duplication in

0368c492d6 gitweb: Change the way "content tags" ('ctags') are handled
The major change is removing the ability to edit content tags (ctags)
in a web browser.

The interface was created by gitweb, while actual editing of tags was
to be done by external script; the API was not defined, and neither
was provided example implementation.  Such split is also a bit fragile
- interface and implementation have to be kept in sync.  Gitweb
provided only ability to add tags; you could not edit tags nor delete
them.

Format of ctags is now described in the comment above git_get_project_ctags
subroutine.  Gitweb now is more robust with respect to original ctags
format; it also accepts two new formats: $GIT_DIR/ctags file, with one
content tag per line, and multi-value `gitweb.ctag' config variable.

Gathering all ctags of all project is now put in git_gather_all_ctags
subroutine, making git_project_list_body more clear.

git_populate_project_tagcloud subroutine now generates data used for
tag cloud, including generation of ctag link, also in the case
HTML::TagCloud module is unavailable.  Links are now generated using
href() subroutine - this is more robust, as ctags might contain '?',
';' and '=' special characters that need to be escaped in query param.
Shown tags are HTML-escaped.

The generation of tag cloud in git_show_project_tagcloud in the case
when HTML::TagCloud is not available is now changed slightly.

The 'content tags' field on project summary page is made more in line
with other fields in "projects_list" table.  Because one cannot now
add new tags from web interface, this field is no longer displayed
when there are no content tags for given project.

0c8c385ef1 gitweb: supply '-n' to gzip for identical output
For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files.  Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.

Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems.  In particular, OpenBSD does not appear to
support it.

Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.

2b1e17237b gitweb: Fix handling of fractional timezones in parse_date
Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.

This was caused by two mistakes:

* sign of timezone was applied only to hour part of offset, and not
  as it should be also to minutes part (this affected only negative
  fractional timezones).

* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
  so fractional part was discarded altogether ($h is hours, $m is
  minutes, which is always less than 60).

Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.

For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of
"Sat Jan 9 00:18:07 2010 +0530".

5e96a847b3 gitweb: fix #patchNN anchors when path_info is enabled
When $feature{'pathinfo'} is used, gitweb script sets the base URL to
itself, so that relative links to static files work correctly.  It
does it by adding something like below to HTML head:

  <base href="http://HOST/gitweb.cgi">

This breaks the "patch" anchor links seen on the commitdiff pages,
because these links, being relative (<a href="#patch1">), are resolved
(computed) relative to the base URL and not relative to current URL,
i.e. as:

  http://HOST/gitweb.cgi#patch1

Instead, they should look like this:

  35a9811ef9 (patch1)

Add an "-anchor" parameter to href(), and use href(-anchor=>"patch1")
to generate "patch" anchor links, so that the full path is included in
the patch link.

While at it, convert

  print "foo";
  print "bar";

to

  print "foo" .
        "bar";

in the neighborhood of changes.

6affdbe677 gitweb: highlight: replace tabs with spaces
Consider the following code fragment:

        /*
         * test
         */

vim ":set list" mode shows that the first character on each line is a
tab:

^I/*$
^I * test$
^I */$

By default, the "highlight" program will retain the tabs in the HTML
output:

$ highlight --fragment --syntax c test.c
        <span class="hl com">/*</span>
<span class="hl com">    * test</span>
<span class="hl com">    */</span>

vim list mode:

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

   1         /*
   2     * test
   3     */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

   1         /*
   2          * test
   3          */

This can be accomplished by specifying "--replace-tabs=8" on the
highlight command line.

3ca7353cab gitweb: remove unnecessary test when closing file descriptor
It happens that closing file descriptor fails whereas the blob is
perfectly readable.  According to perlman the reasons could be:

   If the file handle came from a piped open, "close" will additionally
   return false if one of the other system calls involved fails, or if the
   program exits with non-zero status.  (If the only problem was that the
   program exited non-zero, $! will be set to 0.)  Closing a pipe also waits
   for the process executing on the pipe to complete, in case you want to
   look at the output of the pipe afterwards, and implicitly puts the exit
   status value of that command into $?.

   Prematurely closing the read end of a pipe (i.e. before the process writ-
   ing to it at the other end has closed it) will result in a SIGPIPE being
   delivered to the writer.  If the other end can't handle that, be sure to
   read all the data before closing the pipe.

In this case we don't mind that close fails.

It is needed only to escape attributes of handcrafted HTML elements,
and not those generated using CGI.pm subroutines / methods for HTML
generation.

While at it, add esc_url and esc_html where needed, and prefer to use
CGI.pm HTML generating methods than handcrafted HTML code.  Most of
those are probably unnecessary (could be exploited only by person with
write access to gitweb config, or at least access to the repository).

This fixes CVE-2010-3906

67976c65e0 gitweb: Fix handling of whitespace in generated links
When creating path_info part of link, don't encode space as '+', because
while $cgi->param('foo') translates '+' in query param to ' ', neither
$ENV{'PATH_INFO'} nor $cgi->path_info() do.

This fixes the issue with pathnames with embedded whitespace and
$feature{'pathinfo'} / path_info links.  It is done by using newly
introduced esc_path_info() instead of esc_url() in href() subroutine.

Also while links are more clear not escaping space (' ') characters in
generated links, the trailing space must be URI-encoded, otherwise would
get discarded.

Issue noticed thanks to John 'Warthog9' Hawley.

da4b2432cc gitweb: selectable configurations that change with each request
Allow selecting whether configuration file should be (re)parsed on each
request (the default, for backward compatibility with configurations that
change per session, see commit 7f425db (gitweb: allow configurations that
change with each request, 2010-07-30)), or whether should it be parsed only
once (for performance speedup for persistent environments, though currently
only FastCGI is able to make use of it, when flexibility is not important).

You can also have configuration file parsed only once, but have parts of
configuration (re)evaluated once per each request.

This is done by introducing $per_request_config variable: if set to code
reference, this code would be run once per request, while config file would
be parsed only once.  For example gitolite's contrib/gitweb/gitweb.conf
fragment mentioned in 7f425db could be rewritten as

  our $per_request_config = sub {
  	$ENV{GL_USER} = ($cgi && $cgi->remote_user) || "gitweb";
  };

to make use of this feature.

If $per_request_config is not a code reference, it is taken to be boolean
variable, to choose between running config file for each request
(flexibility), and running config file only once (performance in
persistent environments).

The default value for $per_request_config is 1 (true), which means that
old configuration that require to change per session (like gitolite's)
will keep working.

While at it, make it so evaluate_git_version() is run only once.

When 'remotes' view is passed the 'hash' parameter, interpret it as the
name of a remote and limit the view the the heads of that remote.

In single-remote view we let the user switch easily to the default

enabling the 'remotes' link in the reference navigation submenu.

c7d94cdbe7 gitweb: allow action specialization in page header
An optional -action_extra parameter is given to git_header_html() to
identify a variant of the action that is being displayed. For example,
this can be used to specify that the remotes view is being used for a
specific remote and not to display all remotes.

When -action_extra is provided, the action name in the header will be
turned into a link to the action without any arguments or parameters, to
provide a quick link to the non-specific variant of the action.

00fa6fef63 gitweb: separate heads and remotes lists
We specialize the 'heads' action to only display local branches, and
introduce a 'remotes' action to display the remote branches (only
available when the remotes_head feature is enabled).

Mirroring this, we also split the heads list in summary view into
local and remote lists, each linking to the appropriate action.

The git_get_heads_list now defaults to 'heads' only, regardless of
whether the remote heads feature is active or not.

d0af3734f1 gitweb: Improve behavior for actionless path_info gitweb URLs
Eli Barzilay noticed that

  http://server/gitweb/project/<commit-sha1>

link goes to 'shortlog' view, while 'commit' view would be more
useful, but that 'shortlog' action is more apropriate for

  http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

links.

Therefore for the case when we don't have either action, or filename,
or parent hash [base] in path_info-based URL, i.e. for

  http://server/gitweb/project/<object-id>

link, instead of using 'shortlog' view we allow dispatch() subroutine
to detect type of object and use appropriate action (in most case it
would be either 'commit' action, or 'tag', or 'tree' for top
directory).

8ff76f4c3b gitweb: Move call to evaluate_git_version after evaluate_gitweb_config
Now evaluate_git_version() is inside run_request() to be called for each
request, instead of once per starting gitweb; this currently matters only
when using FastCGI interface (gitweb.fcgi).

This change was done because evaluate_git_version() uses $GIT variable,
which can be set / modified by gitweb config file, but the variable is
modified this way by gitweb config file used in gitweb tests.  Without
this change there is spurious extra output from t9500 test when tests are
run with '--debug' option.

d48b284183 perl: bump the required Perl version to 5.8 from 5.6.[21]
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.

However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:

    sub run_cmd_pipe {
           my $fh = undef;
           open($fh, '-|', @_) or die;
           return <$fh>;
    }

Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):

    t2016-checkout-patch.sh
    t3904-stash-patch.sh
    t3701-add-interactive.sh
    t7105-reset-patch.sh
    t7501-commit.sh
    t9700-perl-git.sh

Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.

The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.

All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.
